Office Action

§DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Priority Acknowledgment is made of applicant's claim for foreign priority based on an application filed in China on 2/20/2023. It is noted, however, that applicant has not filed a certified copy of the 202310151006.8 application as required by 37 CFR 1.55. Election/Restrictions Applicant’s election without traverse of Group I, claims 1-6, in the reply filed on 9/12/2025 is acknowledged. Claim Objections Claim 1 is objected to because of the following informalities: Claim 1 recites the limitation “comprising following components.” Appropriate correction is required. Specification The disclosure is objected to because of the following informalities: It appears that the heading in Table 2 (and Table 2-continued) should refer to thermal performance instead of acoustic performance. Appropriate correction is required. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 4 of U.S. Patent No. US 11,837,210 B1 in view of Zhou (CN 109206961 A). Although the claims at issue are not identical, they are not patentably distinct from each other because claim 4 of U.S. Patent No. US 11,837,210 B1 meets all of the limitations of claim 1 except for a teaching of thermal conductivity and a mass percent of 1%-80% of graphene particles, wherein the graphene particles are bonded to an activated carbon fiber surface of the activated carbon felt through the adhesive, and wherein the zeolite particles are bonded to surfaces of the graphene particles through the adhesive. In addition, Zhou teaches a graphene electricity and heat-conductive coating that comprises by weight 1~10 parts of graphene, 0.5~2 parts of zeolite powder, and 1-3 parts of acrylic resin (an adhesive) (among other components) (Abstract). It would have been obvious to one having ordinary skill in the art prior to the effective filing date of the invention to have combined graphene particles with the zeolite particles in a ratio of 1~10 : 0.5~2 parts by weight as part of a bound coating in the composite material in order to obtain a heat conductive composite material that is useful in the field of semiconductor materials, as suggested by Zhou (Abstract, page 3, lines 24-31, and pages 6-7, lines 31-15).
